The Anglo-Portuguese Army was the combined British and Portuguese army that participated in the Peninsular War, under the command of Arthur Wellesley. The Army is also referred to as the British-Portuguese Army and, in Portuguese, as the Exército Anglo-Luso or the Exército Anglo-Português.

The Portuguese Army is the land component of the Armed Forces of Portugal and is also its largest branch. It is charged with the defence of Portugal, in co-operation with other branches of the Armed Forces. With its origins going back to the 12th century, it can be considered one of the oldest active armies in the world.
